The Hollywood Reporter, the movie is going to star Keri Russell, Ray Liotta, Alden Ehrenreich, O’Shea Jackson Jr., and Jesse Tyler Ferguson. We don’t know which one of them is playing the bear, but
The Hollywood Reporter says the movie will be a “character-driven thriller” from a script by Jimmy Warden and that “exact plot details are being kept under wraps.” There’s obviously going to be some fictionalizing going on here, because the full extent of the original story is that a drug smuggler tossed a bunch of drugs out a plane and then fell to his death when his parachute wouldn’t work (because he was carrying too many drugs), and then a black bear found the drugs and died.
